| 摘 要： | 鸭绿江断裂带两侧分属中国和朝鲜,在其范围内分布着包括五龙金矿、青城子铅锌矿、造岳金矿和检德铅锌矿在内的一批世界知名的大型、超大型矿床.其成矿基底构造为形成于古元古代的辽老摩古裂谷,成矿地层为古元古代形成的辽宁境内的辽河群和朝鲜一侧的摩天岭群,成矿岩浆活动为古元古代和中生代的岩浆侵入事件.成矿的高峰期集中于古元古代裂谷发育活动期和中生代构造-岩浆活动的活化期.朝鲜的成矿空间根据矿产种类的分布及密集程度可以划分为平北金成矿带和检德-惠山铜铅锌多金属成矿带,其中平北金成矿带又可进一步划分为云山-大榆洞金成矿亚带、天摩.造岳金成矿亚带、吉祥一宣川金成矿亚带.在其中国一侧也相应地划分为五龙-白云金成矿带和万宝-桓仁铜铅锌多金属成矿带,两大成矿带各自进一步划分为五龙-白云、岫岩-大孤山、新房-猫岭金成矿亚带和桓仁-二棚甸子、五里甸子.向阳、万宝-张家堡子铜铅锌多金属成矿亚带.未来在辽东地区寻找贵金属和有色金属矿产资源的方向就集中于这些亚带和亚带的局部地段,层控性的铜矿床有可能是未来寻找矿产资源的重大突破点.通过进一步研究对比,有望在辽东地区寻找到铜资源量1 000万吨;铅锌资源量2 000万吨;金资源量500吨. |

| Abstract: | The Yalu River fault zone between China and Korea has a lot of world-famous metal deposits on both sides, such as the Wulong gold deposit, the Qingchengzi Pb-Zn deposit, the Zaoyue gold deposit and the Jiande Pb-Zn deposit. The Paleoproterozoic Liaolaomo paleorift, the Paleoproterozoic strata (Liaohe Group in China and Mo-tianling Group in Korea) and the Paleoproterozoic-Mesozoic igneous activities make up the metallogenic geological background of this area. There existed two metallogenic peak stages, i. e., Paleoproterozoic rifting and Mesozoic tectono-magmatic activation. The ore-forming belts in Korea can be divided into the Pingbei gold ore belt and the Jiande-Huishan Cu-Pb-Zn polymetallic ore belt, and the former ore belt can be further divided into the Yunshan-Dayudong, the Tianmo-Zaoyue, and the Jixiang-Xuanchuan gold sub-belts. The ore belts on China's side are composed of the Wulong-Baiyun gold ore belt and the Wanbao-Huanren Cu-Pb-Zn polymetallic ore belt. Among them, the Wulong-Baiyun gold ore belt is further divided into the Wulong-Baiyun, the Xiuyan-Da-gushan and the Xinfang-Maoling gold sub-belts, and the Wanbao-Huanren Cu-Pb-Zn polymetallic ore belt is further divided into the Huanrenerpengdianzi, the Wulidianzi-Xiangyang and the Wanbao-Zhangjiabaozi Cu-Pb-Zn sub-belts. These sub-belts constitute the most favorable places for finding mineral resources in Liaodong area, with the most hopeful metallic deposits being stratabound Cu ore deposits. 1 000 million tons of Cu, 2 000 million tons of Pb-Zn and 500 tons of Au are expected to be found through a comparative study on both sides of the Yalu River fault zone. |
